2.2 Linear Displacement

Linear motion commonly occurs when detecting the position of an electronic switch, button-press, tracking objects that slide on tracks, and in liquid level detection. For long travel, this type of motion is commonly monitored using arrays of sensors such are described in Linear Hall-Effect Sensor Array Design and Magnet Selection for Linear Position Applications.

Figure 2-6 Linear Motion Using a Bar Magnet

To simulate linear magnet travel, select "Linear Displacement" from the top-menu.

Figure 2-7 Linear Displacement Function Selection

The resulting prompt appears as shown in #GUID-6ABF8525-7E66-4683-A69D-8BC6B2AC922A

Figure 2-8 Linear Displacement Function User Inputs

Magnet travel occurs in a smooth fashion from the initial position entered in the Magnet Alignment section, and steps evenly to the final (X,Y,Z) position in the Magnet Motion section. This travel is commonly along a single axis, but the magnet may travel in all three dimensions simultaneously as needed.
